Abstract :
In this paper, a new approximation is proposed to design fractional order digital differentiator using fractional delay filters. New approximation improves the design accuracy of conventional fractional differencing for wideband compared to existing approximations. Proposed new approximation is applied to see relatively small error for wideband.
